摘要
基于回传射线矩阵法,研究两缺陷桩在半正弦脉冲激振力作用下桩顶的速度波,基桩的缺陷用横截面积的变化来模拟.比较缺陷桩与完整桩的桩顶速度波,分析缺陷程度对缺陷桩桩顶速度波的影响,得出一些有意义的结论.
Based on the method of reverberation matrix, the velocity wave of two-defective pile head under semi-sine impulse exciting is discussed in the paper. The defects of pile are simplified by changing the cross -section areas of defective elements. The velocity wave of defective pile head and intact pile head are compared. The velocity wave of defective pile head is analyzed, which is effected by defect extent. Many significant conclusions are obtained.
